What is the drug of choice for bradycardia?
The drug of choice is usually atropine 0.5–1.0 mg given intravenously at intervals of 3 to 5 minutes, up to a dose of 0.04 mg/kg. Other emergency drugs that may be given include adrenaline (epinephrine) and dopamine.
What is the first line drug for bradycardia?
Atropine. In the absence of reversible causes, atropine remains the first-line drug for acute symptomatic bradycardia (Class IIa). In 1 randomized clinical trial in adults (LOE 2)5 and additional lower-level studies (LOE 4),6,7 IV atropine improved heart rate and signs and symptoms associated with bradycardia.
At what heart rate do you give atropine?
2. Administer Atropine 0.5 mg IV/IO repeating every 3-5 minutes to a total dose of 3 mg IV/IO, until a heart rate of greater than 60 /minute is reached. 3. Transcutaneous pacing (TCP) when available may be initiated prior to establishment of IV access and/or before Atropine begins to take effect.
When do you give atropine vs epinephrine?
Epinephrine provides a greater amount of hemodynamic support. Patients dying with bradycardia aren’t truly dying from bradycardia itself, but rather from cardiogenic shock (low cardiac output). Atropine offers these patients an increased heart rate, nothing more.
Which of the following drugs is the first line of treatment of symptomatic Bradyarrhythmia intraoperative?
Atropine sulfate is the first-line drug for acute symptomatic bradycardia and an initial dose of 0.5 mg is recommended.
Why is atropine contraindicated in hypothermia?
The authors cannot recommend atropine therapy in cases of hypothermic bradycardia, because of its lack of effect on the heart rate in hypothermia.
When should you not give atropine?
Atropine should be avoided with bradycardia caused by hypothermia and, in most cases, it will not be effective for Mobitz type II/Second-degree block type 2 or complete heart block.
What medicine regulates heart rate?
The two types of medication most commonly used to slow a racing heart are: Beta-blockers. Calcium channel blockers.
